MECHANICAL MOVEMENT AND ENGINE.

Application led October G, 1924. Serial No. 741,919.

/ 1o all whom t may concern:

Be it known that I, JOHN C. WILLIAMS, a citizen of the UnitedStates,land a resident of Miami, county of Dade, State of Florida, haveinventeda certain new and useful Improvement in Mechanical Movements andEngines, of which the following is a complete specification.

The present invention relates to power' devices, and particularly toapparatus designed to utilize a relatively small mechanical effort forthe driving of machinery through the medium of gearing and levers or thelike so arranged as to increase the mechanical advantage possessed bythe driven'element from which connection is made to the machinery to beoperated.

Accordingly, one object of the invention is to provide an improvedmechanical movement consisting of a driven gear wheel operated by alever and mechanism acting to impart a circular movement to the leverabout an intermediate fulcrum point, for intermittently engaging theteeth of the gear wheel and, by a prying effort, imparting a step bystep movement to the wheel. It is also sought to devise animproved formof apparatus utilizing the mechanical movement just referred to, inwhich a set of levers and' operating members are employed for lactuatingthe gear wheel, the arrangement ofthe levers being so carriedV out andtheir operation so timed as to develop a nearly continuous movement ofthe driven gear wheel.. i

Wvith the foregoing objects in view, the invention will now be describedby reference to the accompanying drawings illustrat-ing one form ofconstruction which I have rdevised for embodying the proposedimprovements, after which those features and combinations deemed to benovel will be particularly set forth and claimed.

In the drawing- Figure 1 is a side elevation illustrating an apparatusconstructed in accordance withthe present invention g Figure 2 is a planview of the same;

Figure 3 is an end elevation of the apparatus;

e Figure I is an elevation of the driven gear member of the apparatus,having represented thereon the different positions ocoperative endsofthe levers by which rotadriven.

, Figure 2.

Referring now to the drawings in detail, these show a constructioncomprising a base plate on one end of which is supported a standard orbracket l2 providing a bearing 18 for theshaft lof a master bevel gearwheel which may be rotated manually by means of a crank 16 on the outerend of the shaft 14: and provided with a suitable handle 17. At theupper end of the standard 12 the same is forked as illusw trated inFigures 2 and 3, and in the ends of therforked portion are mounted stubshafts 18 in downwardly inclined position, for journaling a pair ofbevel pinions 19, 20, which are meshed with the upper portion of thegear 15. At its base, the standard 12 is also provided with a pair ofupwardly inclined stub shafts 21 for journalingl a pair of bevel pinions22, 23, which are meshed with the lower portion of the gear 15.

Near the other end of the base plate 1() is mounted a pair of bearingstandards 25 for supporting a transverse shaft 26 to which is keyed apair of gear wheel members 27, in spaced relation for accommodatingbetween them a pulley element 28 to which a drive belt (not shown) maybe applied for transmitting power to any appliances to be Since the gear.wheel members 27 are duplicates and keyed to the same shaft, theyoperate in effect as a single gear wheel member in driving the shaft 26and pulley 28 in response to the driving action imparted thereto fromthe bevel gear 15 through the bevel pinions, in the manner now to bedescribed. f

Intermediate the standards 12 and 25, is mounted, on the base plate 10,a pair of frame members 80 opposite each of the gear wheel members 27and each of the frame members is provided with a pair of suitable ballbearing members 32 for slidingly accommodating the operative orgear-tooth engaging ends of a set of levers 33,v 84, 35 and 36 which areconnected by universal or ball and socket joints, as indicated at 31(see Figure 5) to the bevel pinions 23, 20, 19 and 22, respectively. Itwill now be seen that the angular arrangement of the shafts itu 18 and21, and the elevation of the shaft 14, are such as toproject theoperative end of each of the levers 33 to 36 into operative engagementWith the teeth of the gear Wheel members 27, and toalternatively retractsaid levers from engagement with the teeth of said gear Wheel members,once for each revolution of the corresponding bevel pinions. Thisfeature is illustrated in Figure l, itVV being further noticed that theinclination of the bevelY pinions and the location of the bearings 32for the levers are such that the' levers are retracted from the gearWheel members 27 during the travel of the lioints 31 of the leversthrough the lovver pathsof their movement along with the bevel pinions,while the operativeY ends ofsaid levers are enggaged with said gearWheel members during the travel of said joints 31 through the upperpaths of their movement with the pinions.

The operation of the apparatus is carried out by the rotation of thecrank 16', thereby7 producing rotation of the master gear 15 and thebevel gearpinions 19, 20, 22 and 23, which rotation may, of course,taleplace in either direction, according to the Ydirection in Which it isdesired to turn the shaft 26. As the bevel gears are rotated, this Willyimpart corresponding rotation to the joints 31 and corresponding endsof the levers 33 to 36, with the result that the inner or opera, tiveendsV of said levers are correspondingly rotated in the same directions,and this rotation is obviously accompanied by a sliding movement Withinthe ball bearingsV 32 as required by the retracting and advancinUrmovement of the levers, due to the inclined positionsy of the'bevel gearWheels.

Vtssuming now that a counter clockwisev movement is given the Wheel 15,which will producevcloclrvvise rotation of the bevel gear Wheels, andsimilar rotation of the inner or operative ends of the levers connectedto. That is to say, a circular motion is imparted to the ends of thelevers connected to the bevel gear Wheels. and a similar circular motionis imparted to the other or operative ends of said levers, and thearrangement of the bearings ofthe levers is suoli that this circularmotion is that required for swinging the operative ends ofthe leversinto and out of oositicn between the successive teeth of the gear Wheels27, as has been illustrated diagrammatically in Figure l. In` thedirection of operation being considered, Fig? ure e illustrates theoperative end of the lever 33 moving from an entirely disengaged' orinoperative position andjust starting in the direction for engagementwith thenext sncceedijngtooth of the corresponding gear Wheel member2,7. `The operative end ofthe lever 34C has just started to move inbetween the teeth of the gear Wheel and is commencing its operativerotative engagement with .one of the teeth thereof. The operative end ofthe lever 35 has just completed its operative driving engagement Withone of the teeth of the other gear Wheel member 2, and is beginning its`retracting movement out of engagement with the Wheel; and, finally,Vthe operative end of the lever 3G has half Way completed this operativemovementir-the arrows in Figure a indicating the direction of circularmotion of the operative ends of said levers. It Will be understood inthis connection that the ends ofthe leversV are not in actual contact orengagement with the teeth ofthe gear Wheels 27 during the entire travelrepresentedbythose portions of the small circles which inteiseot thegear teeth in Figure ll, as during a portion of this movement the leversare being actuated longitudinally for effecting the slight advancing andretracting movement, as has been above explained. hislength- Wisemovement of the levers is of advantage, in that it facilitates themovement of the operativev ends of the levers into andout of operativeposition, and makes possible the use of a wheel of the ordinary gearWheel type. I

From the foregoing it will beapparent that a simple and practicalarrangementhas been provided for carrying out the desired objects of theinvention, one of the important features of which is the application ofa comparatively small mechanical effort for the driving of heaviermachinery, the system and arrangement of levers employed being i plainlyVadapted to greatly increase the mechanical advantage which is gained`in the operation of thegear Wheel members 27 in the mannerdescribed..`4V The mode of operation is in some respects similar to thatset forth in .Patent No,i 866,761 issued to me on September 24, 1907,but the `present arrangement and construction are-very much superiordueA to the fact that it is possible to accumulate momentum in theoperation of theimproved apparatus on account of the use of a mastergear 15 for operating the smaller gears connected vWith the operatinglevers. The improved construction furthermore is more nearly noiselessthan that of I the type illustrated yin the patent referred to, and maybe operated with equal efficiency in either direction.
